Hey i just used this system variable to get my guppi SoG workunits running faster,

my failure, it´s for cuda only i think. Is there a chance that somebody could test it on cuda workunits here ?

If there is no variable set the value is 8 , but whats happening it´s 16 or 32 ?

Anyone tested before ?

Greetings (got no cuda workunits on the run to test.)

i tested it quickly, but there´s no performance/gpu usage increase.

Maybe on two workuints at the same time ?

Iam checking that.

------------

It´s hard to tell, but ->

There´s no powerloss or gain on setting this enviromental variable.
